SAMUEL GAME. OF PITTSFZELD, MASSACHUSETTS, ASSIGNOB TO CRGMYPEON 1S2 KHOWLES LOUIE ii /0312 .2,

Application filed June 16, 1924.

This invention relates to take-up mechanism for looms and more particularly to the change gear devices by which the number of picks taken up per inch may be varied.

it frequently happens that a loom is called upon to weave fabrics having a variety of picks per inch and it is necessary to change the gearing in each instance so that the advance of the fabric may be kept in step with the number of picks required. l l here it is desired to use the same loom for weaving fabrics rangin anywhere from sixteen to two hundred pic per inch it has i rmerly been necessary to deep on hand a is her of change gears. Accordingly ii object of present inve.

a ently at ache d a locm with per de- -h will'sii the numb [lie loom require.

A more specific object of my invention is to introduce shifting gears between some regularly driven part of the loom and the take-up mechanism.

A further object of my invention is to provide for moving the shifting gears by means which will give a visual indication that the gears are in proper position. 7

A still further object of my invention is to provide shifting gears for the purpose mentioned which may be driven in either direction so that the cloth may be fed backwardly when picking out a mispick.

l/Vith these and other objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

In the accompanying drawing wherein one form of my invention is shown,

Fig. 1 is a side elevation of a loom having my invention applied thereto,

Fig. 2 is a detailed enlarged view showing the shifting gears and the manner in which they are mounted,

Fig. 3 is a rear view of the shifting gears looking in the direction of arrow 3, Fig. 2,

Fig. 4 is a longitudinal section on line 4-4 of Fig. 3, and

Fig. 5 is a fragmentary vertical section taken on line 5--5 of Fig. 2.

Referring more particularly to the drawing it will be seen that I have provided a loom side on which is mounted a stud 11 to nsion is to SF "WORCESTER, MASSACHUSETTS, CORPORATION OF MASSA- TAKE-UE MECHANISIVI.

Serial No. 720,146;

revolution of shaft 22 the gear 12 will be moved the space of one tooth and the takeup roll will be given an advance movement the extent of which is determined by the ratio of the gears 14, 15 and 16.

Upright shaft is driven by driving bevel gear 26 and the clutch mechanism indicated at 27, the latter being controlled by lever 28. Sliding on shaft 25 is a sleeve 29 having upper and lower bevel gears 30 and 31., respectively, rigid therewith and movable endwise through manually controlled lever 32. The matter thus far described is old and for a more complete description of the same reference may be had to Patent No. 810,680, issued to Ryon Jan. 23, 1906.

My invention relates more particularly to the mechanism interposed between shaft 22 and the driving bevel gears 30 and 31. In carrying out my invention I provide a stand bolted or otherwise secured to the loom frame and adapted to receive a cap or cover 41 which is fitted to the frame and held thereto as by bolts 42. Split bearings 43 and 44, respectively are provided, one half of each bearing being on the stand 40 and the other half being on the cap 41. Bearing 43 receives shaft 45 to which is fastened gear 46 and a somewhat larger gear 47 These gears .are located within the housing formed by the stand and its cap and are driven by means of bevel pinion 48 which is fastened to shaft 45 and positioned to mesh with one or the other of the driving bevel pinions 30 or 31 according to the position of lever 32.

Bearing 44 receives the rear end of shaft 22 and as shown in Fig. 4 the latter is provided with a. key-way 49 which receives key 50. A gear 51 has a sleeve 52 formed integral therewith which is provided with a slot 53 to receive key and permits said gear 51 to slide on the shaft 22. A second gear 54 is secured to the sleeve 52 by means of asecond key 55 the gears 51 and 54 thus being secured together and movingin o l will be in mesh.

unison. The gear 54: may be driven onto the sleeve 52 and spaced sufliciently from gear 51 to provide room for a control arm 56 the inner end of which fits loosely over the sleeve 52 and positioned by the said gears'51 and 54. The outer end of the arm 56 has pivoted thereto a handle 57 the under side of which has extending therefrom :1 lug 58 which is positioned to be received by one or the other of detents 59 and 60, respectively formed in the cap all. The detents open into a slot 61 which permits movement of arm 56 in a direction parallel to shaft 22. The gears 46, i7, 51 and 5a are so related that when lug 58 is in (letent 59, large gear 47 will mesh with small 51 on shaft 22 and when the lug is in detent 50 the gears 46 and 54 will be in mesh. The latter gears are preferably formed with an equal number of teeth so that for each revolution of shaft l?) shaft will be given one revolution while gear l? may be made twice as large as gear 51 so that for each revolution of shaft L5 shaft 22 will be given two revolutions.

it the loom is to be used for weaving coarse fabric, gears at? and 51 will be in mesh so that the change gears previously r ferred to will give the take-up roll a rela ively 'l ast movement, but it the fabric is liner with more picks to the inch, the device will be shifted so that gears 46 and In this way it is possible'to get the same range of picks with alt the number ot change gears. lVhen is desired to shift the gears the handle of will be raised "from the position shown in full lines, Fig. 3, to the position shown in dotted lines and the arm 56 moved so that lug 58 will fit into the other detenn.

In this way the weight of the lever holds the lug in such position as to prevent accidental sliding movement of the shifting gears.

From the foregoing it will be seen that I have provided a very simple set of shifting gears which make it possible to get a large variety of numbers 01": picks with a reduced number of change gears. it will also be noticed that if lug 58 is in an intermediate position between the detents the handle 57 will be held outwardly and thus give a visual indication that the shift gears are not in proper mesh.

Having thus described my invention it will be apparent that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I do not wish to be limited to the details disclosed herein, but what I claim is:

i. In a loom, a take-up mechanism, a driving shaft, a plurality of gears moving in relatively fixed planes, sliding gears one only of which is in mesh with one of the first named gears, and means to shift the latter gears, said means including a weighted member having a lug to cooperate with a plurality o1 notches to position said shifting gears with respect to the gears rotating in fixed planes. 7

2. In a loom, a take-up mechanism, a set of driving gears rotatable in relatively fixed planes, a set of shifting gears to cooperate one by one with one or another or" the first named gears, a handle to move said shifting gears, and means to give said handle a diiierent position when the gears are pr0prly meshed from the position it occupies when the gears are improperly meshed.

In testimony whereof I have hereunto affixed my signature.

SIXMUEL GAME.
